I have 6000 rounds of .556 and 223 brass, once fired, for sale. Various headstamps, but if I had to guess, most is Federal. Will sell any amount you want for ten cents per round. All 6000 is $600 picked up in Warner Robins. Shipping would be extra. Will sell smaller amounts if you don't need that much. Wallace in Warner Robins, 478-918-5392
